Musannaf Ibn Abi Shayba 28:375

'Abd al-'Aziz ibn 'Abd al-Samad al-Qummi narrated to us, from Malik ibn Dinar, from al-Hasan, that a man asked the Prophet, may Allah bless him and grant him peace, for a bridle of hair from the fay' (spoils of war). The Messenger of Allah, may Allah bless him and grant him peace, said: "You are asking me for a bridle of fire. It was not appropriate for you to ask me for it, and it is not appropriate for me to give it to you."
